High Temperature GPC Analysis of a Polypropylene Copolymer

Tosoh Bioscience has produced an application note determining the molar mass averages and polydispersity of two polypropylene random copolymer samples via refractive index (RI) detection using the EcoSEC High Temperature GPC System and TSKgel...

Trends and Applications in GPC Polymer Analysis

Gel permeation chromatography (GPC) is a valuable and well established tool for the chemical industry when it comes to the determination of the molecular weight and the molecular weight distribution of polymers.

Analysis of Polymers for Therapeutics

Tosoh Bioscience has produced an application note demonstrating how GPC was applied to analyse and differentiate the molar mass averages and distributions of four block copolymers intended to be used in a polymer-based therapeutic.

Understanding GPC/SEC - What do you need to know before injecting a sample?

So you're thinking of using gel permeation chromatography (GPC) for your analyses, but before you dive in just what information do you need to know before your first sample injection?
